Hello there,

 

I've got a problem with my default route in unRAID. After every reboot, the second NIC is used for the default route configuration. I have to change it after every reboot back to my first NIC. Is there a way around that?

 

 

 

Thanks in advance!

How are you doing that? It must be done on Settings -> Network Settings -> Interface Rules (reboot required)

Perhaps I did not express myself properly. I change the default route after each reboot as described above.

 

Gonna check the GUI later, if somebody answers my question regarding my "File not found." GUI problems!

Are you doing it in the Interface rules? Doesn't look like it since it requires a reboot.

So my interface rules are set as follows: 

 

But after each reboot, unraid sets the default gateway to br1, like this: 

It should use 192.168.1.210 via br0!

 

I can't delete the default route via GUI, so I do it after every reboot by hand via SSH.

 

What am I doing wrong?

I misunderstood your issue, sorry, not a network guy so something I can't help with.

Some docker, which are part of the network via br0 can't resolve DNS. I can't figure out what's wrong. Pleas help!

I've pinned the issue down to all the dockers with a static IP address and br0 as their network. They can't resolve any address. What am I missing? Do I have to configure the second NIC any different to not intervene with the traffic of br0 or sth like that?

 

Has anyone an idea?

I've solved the docker issue for now. I changed the following setting:

There was a second entry for br1  with no gateway etc. I've unchecked the entry and restarted the docker service. The dockers are resolving the addresses correctly now. I have no clue, why a docker with an IP in the 192.168.1.0/24 net would try to communicate via br1 and its not available gateway. It's a mystery to me.

My problem from the first post isn't resolved yet. Maybe someone could help? Thanks a lot in advance!

I have the same problem. I added an additional physical NIC for a lab network. I only used the interface for a short while and do not have anything operating on that network anymore. The cable is disconnected and the interface shutdown. However, every time the server reboots it starts up with the default route assigned to the secondary NIC. I have to manually add the default route to the primary gateway and shutdown the secondary NIC.
 

It happens every reboot.

I have the same exact problem.   My main network is 10.168.10.0/24 which on my unraid box is on the br0 interface.  As well, I have interfaces for non-internet accessible VLans (br2, br2.200).  Whenever I reboot, unraid changes my default route to the 10.168.200.1 IP address on the br2.00 vlan interface. 

 

I can add a default route to the 10.168.10.1 address using the GUI, but I can't remove the default one on  br2.200.  I have to SSH in and run the command

root@Nas:~# route del -net 0.0.0.0 gw 10.168.200.1

 

This happens on every reboot, with no way to have the default I set stick to 10.168.10.1 after a reboot.

I am having the same issue as well. I've deleted my network config on my flash drive multiple times but it always wants to use my secondary NIC as the primary default route upon reboot. Does anyone have a fix?

Is there a solution for that?

I have the same Issue, on every reboot my default route go back to the NIC in the PCI card instead of the integrated.

 

Thanks

Do you have the integrated NIC set as eth0?

Yes. 

I fix the issue by removing the gateway on the second nic. 

When both nic has gateway second nic was alway use

You can only use one gateway, or it will cause issues
